Authorities are currently searching for a "person of interest" with connections to the felon who shot and killed Jersey City Police Officer Melvin Santiago yesterday morning, officials said.

Lawrence Campbell, the man police say fatally shot the 23-year-old officer, was wanted in a murder. A named Daniel Wilson is also being sought in the same murder, Mayor Steven Fulop said at a press conference yesterday.

“The Jersey City Police Department has been applying high pressure and aggressively searching for Daniel Wilson for the past three days,” Fulop said, although no other details were provided.

The Jersey City Police Department and Hudson County Prosecutor's Office have not yet released information about which of the other 14 murders this year in which Wilson is being sought.

Yesterday, Campbell, 27, of Grant Avenue, shot and killed Santiago when Santiago responded to a reported armed robbery at the Walgreens pharmacy at Communipaw Avenue and Kennedy Boulevard. Campbell was shot by other responding officers and pronounced dead at the scene.

Santiago's death is the 15th murder in Jersey City this year; he is the 39th JC police officer to die in the line of duty.

Of this year's 14 murders, ther have been no arrests in five. Some of the most recent murders include the shooting of 19-year-old Christopher Lemoine on Lembeck Avenue on July 3 and an incident on June 6, in which Jamal Cooks, 22, and Shawn Spencer, 21, were fatally shot while in a vehicle on Van Nostrand Avenue.

Jersey City has had five more murders in the first six months of 2014 than it did last year. There were only seven homicides in all of Hudson County in the first half of 2013, and 20 by the year's end, 18 of which were in JC.
